All about ski lifts, tramways and gondolas

No one was injured when a downbound cabin detached from a haul rope near the Swiss town of Schwyz this morning. The empty gondola fell some 60 feet into a pasture and was heavily damaged. Approximately 50 people in other carriers were brought into stations normally and the gondola was closed. It appears the incident happened at or near one of the lift’s 16 towers.

The gondola is a 2014 Garaventa model with CWA Omega cabins and torsion grips. An investigation will be undertaken by the Swiss Transportation Safety Board. The company which operates the lift, Rotenfluebahn Mythenregion AG, says it will not reopen the system until it is cleared to do so and the rope is inspected for damage.

Update 10/21: The operator issued a statement blaming the accident on high wind. The affected cabin collided with the tower before falling. The installation was already in the process of being cleared of riders when the incident occurred, a process which takes 20 minutes. The gondola remains temporarily closed.

As so often when accidents happen many people will react that equipment now is built in a flimsy way with the big interesst that manufacturing management is more concerned about stuffing more money in to there pockets. That is simply not true and I responded to some of comments made in the Blick Swiss Paper that how come this reasoning for profit always comes up with the dumb argument about profit being the only interesst. This was a rather lucky accident and much can be learned from this incidence.
At the same time it is a fact that even within our own country equipment is running that is outdated and is in poor operating condition for more of the cause to make money then for safety.

How does that happen? Grip force is applied by the springs/washer pack, etc. The grip acts independently from the weight of the carrier. And it sounds like the carrier striking the tower caused the detachment.

Easiest explanation, what does a dentist do when he extracts a tooth? With his pliers he puts pressure in each and up direction until the darn thing gives way. A cabin and grip gets tossed in every direction including uplift that basically tries to lift the grip and cabin up and off the cable. It is that up lift and yes for a split second puts pressure on the spring and washer pack in the opposite direction. We also know where wind uplift had the force to lift tram cabins off the track rope. .
